The purpose of godlike beings known as humans is one:

The purpose of godlike beings known as humans is one: to become gradually perfect as God the Father, to become a god by grace, to attain theosis, deification, Christification, Trinification. 

But how is this goal to be attained? Through the evangelic virtues of faith and love, hope and prayer, fasting and humility, meekness and compassion, love of God and neighbour. 

Pursuing these virtues, man transfigures his deformed soul, making it beautiful; it is transformed from something dark into something Godlike. He transfigures his body into a temple that can accommodate his Godlike soul.

+ St Justin Popovic
